Upper Limb Function Improvement in Tetraplegia Using Gravity-Balanced Exoskeleton Robot Training

A preliminary study evaluated gravity-balanced exoskeleton robot training for patients with tetraplegia, showing significant improvements in shoulder and elbow muscle strength and range of motion over six training sessions. While functional task performance improvements were observed, they were not statistically significant, suggesting the device shows promise for motor recovery despite limitations in translating to daily activities.
